Small-molecule perturbation of competing interactions between c-Myc and Max

Abstract

The oncogenic transcription factor c-Myc undergoes coupled binding and folding of its basic-helix-loop-helix-leucine zipper domain (bHLHZip) upon heterodimerization with its partner protein Max. The latter exists in two isoforms: p21, which homodimerizes poorly, and p22, which homodimerizes well. We show that the effect of 10058-F4 (a small-molecule that binds disordered c-Myc monomers and disrupts the c-Myc-Max complex) on both c-Myc-Max heterodimerization and DNA binding is dependent on the nature of the Max isoform. In the presence of p22 Max the effective inhibitor concentration is lower than in the presence of p21 Max, as the p22 Max homodimer formation affects the thermodynamics by competing against the c-Myc-Max heterodimerization event.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The c-Myc inhibitor 10058-F4 prevents the c-Myc-Max interaction and inhibits transcription of c-Myc target gene expression.

    “To monitor the effect of inhibiting c-Myc activity we administered the specific c-Myc inhibitor, 10058-F4, which prevents the c-Myc-Max interaction and inhibits transcription of c-Myc target gene expression32.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
